What is difference between:
- Why I am studying?
- Why am I studying?
What is difference between:
The first one is not really a well-formed question in English. Placing the verb right after the interrogative word is the usual way to create an interrogative sentence. Thus: "Why am I studying?", "Where is the station?", "How does this device work?", "Who can lift the stone?"
The other word order would make sense in a clause, but not as a stand-alone sentence. Thus: "I wonder why I am studying," or "She asked me why I am studying." Notice that these sentences are not questions, but statements.
